WELL-STRAIN ER.

SPECIFICATION forming part of Letters Patent No. 604,651, dated vMay 24,1898 Application filed September 22,1897. Serial 1% 662,642. (Nomodell)T0 at whom it may concern: Be it known that I, JOHN BOOTH, a citizenresiding at Bellville, in the county of Austin and State of Texas, haveinvented certain new and useful Improve-1 ments in Well-Strainers; and Ido hereby declare the following to be a full, clear, and eX- actdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. My invention,relates to improvements in well-strainers, and has for its object toprovide a well-strainer of such a construction that by simply varyingits size it may be adapted for use in large or small wells and byvarying shape, and that without modifying the essential features of thestrainer;

My invention will be clearly understood by reference to the accompanyingdrawings, wherein the same parts are indicated by the Figure 1represents a side elevation of a portion of a section of well-strainerconstructed according to my invention in a hexagonal form, and Fig. 2represents an end elevation of the same. Fig. 3 represents a viewsimilar to Fig. 2, showing another form of strainer. Fig. 4 represents aView similar to Figs. 2 and 3, illustrating still anotherform ofstrainer; and Fig. 5 "represents a side elevation of the cylindricalform of strainer shown in Fig. 4.

In Figs. 1 and 2, A represents 'a strainer of a hexagonal form, composedof rectangular side pieces A, beveled at their side edges and fittedtogether, asv at a, and held together by any suitable means. Each ofthese side pieces A is provided with a plurality of larger, preferablycircular, openings A", which extend about halfway the'rethrough from theouter side and connect with smaller, prefer ably circular, openings a,which extend to the inner side of the side piece A. Within the bottom orinner end of the larger opening A and over the'inner end of the smalleropening a is fitted and secured a piece of wire-gauze a and over theouter end of the, larger opening A is also fitted another pieceof-wire-gauze a which is suitably secured in position upon the sidepiece A. Within the space between the two pieces of wire-gauze a and ain the inner and outer ends, respec wells of any desired tively, .of thelarger opening A 1s preferably placed a filling of sponge or othersimilar porous, material, as shown at a in Figs. 1 and 2. One endof thestrainer rests upon the bottom of the well in practice, and the water orother liquid in order to enter the hollow space within the strainer mustpass through the openings A and a". The openings A, leading to the outersides of the strainer, being larger, present a larger filtering area forthe water to pass through, and. the inner openings a", being smaller,present a' contracted space for the escape of the water to the interiorof the strainer, thus insuring'a perfect filtration. v I c When thefiltering material and the wire gauze become so 'cloddedwith sediment asto retard the operation of the strainer, the whole strainer may bereadily lifted bodily from the.

well and cleaned, or the Y may be removed and new material put in itsplace, and the strainer may then be replace in the well with ease andsimplicity. I

In Fig. 3, B represents astrainer of a quad- 1'angular.form-that is,made up of 'four side pieces B of equal width, having their edgesoverlapping and secured, together in any'suitable manner, as at b. eachprovided with a plurality of larger outer openings B and smaller andwith pieces of wire-gauze b and I) over the inner and outeropenings,'respectively,

-and-spon'ge'or similar filtering material b between the saidv pieces ofwire gauze, all con structed and arranged in a precisely similar manner.to the corresponding parts shown in Figs. 1 and 2'and above described.;

.In' Figs. 4 and 5, 0 represents a strainer of a cylindrical form andillustrates such astrainer as-made of molded cement or a section ofterra'-' cotta pipe. In this form of strainer the. required number ofopenings 0 and 0 are arranged at properintervals upon the shell of thestrainer, and the pieces of wire-gauze c not be used, as desired,asalso, however,

would be the case with-the forms her'einbefore described. v

The forms of strainers shown in Figs. 1,-2,

old filtering material.

The side pieces B are inner openings b and c are preferably molded intothe-shell" of the strainer.

The filtering material of shownmay or may and 3 may be made of pieces ofheavy lum-,

in, as general form'may be changed at will tosuit conditions withoutdeparting from the spirit,

of my invention. Not only may the general shape of the strainer bevaried, but the size as well.

Having thus described my invention, what .I claim, and desire to secureby Letters Patent of the United States, is

1. In a well-strainer, the combination of a hollow shell orcasing madeup of-'a plurality of sections fitted together, and provided externallywith a plurality of, larger openings leading partially therethrough andinternally with a corresponding number of smaller openings leading tosaid larger eriternal openings; a'strainer covering the passage betweeneach Y larger'and' corresponding smaller opening;

arid a strainer covering each larger opening, substantially asdescribed.-

2. In a well-strainer, the combination with a .hollow shell or casingmade of cement molded into the desired shapeand provided externally witha plurality of larger openings leading partially therethrough,'and-internally with a corresponding number of smaller openings leadingto said larger external openings; sheets of wire-gauze covering theinner ends of said smaller openings, and other sheets of wire-gauzecovering the outer ends of said larger openings, said sheets of gauzebeing embedded at their edges in said cement, substantially asdescribed. I

. 3. In a well-strainer, the combination with a hollow shell or casingmade of cement, molded into the desired shape and provided externallywith a plurality of openings leading partially therethrough, andinternallywith smaller openings leading to said external openings,sheetsof wire-gauze covering the outer ends ,of said smaller openings,and other sheets of wire-gauze covering the outer 'ends of said saidsheets of gauze being larger openings, embedded at their edges in saidcement casing, and a porous filterin g materialfilling the space betweenthe parallel layers of wiregauze, substantially as described.
